Unlike the common shaved ice or cotton candy sold outside, the ice products sold by Aunt Yan in this area not only follow the traditional old-fashioned recipe, but also use an ancient ice-making machine that is one of the few remaining relics. The three-colored ice made with this machine is dense and refreshing, leaving a lasting memory after consumption. Moreover, the traditional oil paper-wrapped ice bars are elegant and refined, evoking nostalgia. Even foreigners who try them can't help but have a taste.
